Docker方式部署

配置 prometheus.yml

cat /tmp/prometheus.yml
# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']

运行Prometheus
docker run -p 9090:9090 -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
访问
http://ip:9090

可视化方案Grafana

prometheus多数情况下需要结合Grafana工具来达到可视化效果，Grafana是一个开源的度量分析和可视化工具。

下载Grafana

docker方式部署
docker run -d --name=grafana -p 3000:3000 grafana/grafana

docker客户端监控

cAdvisor（Container Advisor）用于收集正在运行的容器资源使用和性能信息

GitHub介绍

客户端部署

docker run -d \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:ro \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--volume=/dev/disk/:/dev/disk:ro \
--publish=8080:8080 \
--detach=true \
--name=cadvisor \
google/cadvisor:latest

配置/tmp/prometheus.yml

cat /tmp/prometheus.yml
将配置添加到后面
......
# 添加新主机
  - job_name: 'docker'
    static_configs:
    - targets: ['172.16.230.17:8080','192.168.20.157:8080']
